Fig. 10 is a cross-sectional side view showing another embodiment of a discharge container according to the present invention;

An embodiment of a discharge container according to the present invention will be described below with reference to the drawings. In the following description, as shown in FIG. 1B, the side on which the discharge cap (reference numeral 3) is positioned with respect to the barrel (reference numeral 1a) is referred to as the upper side, and the opposite side is referred to as the lower side.

The discharge container of this embodiment comprises a container body 1, a check valve 2, a discharge cap 3, and a cover cap 4, as shown in FIG.

The container body 1 includes a cylindrical body portion 1a rising from a bottom portion (not shown) and a shoulder portion 1b connected to the upper end portion of the body portion 1a and having a diameter that decreases upward. A filling space S1 for containing contents is provided inside the shoulder portion 1b. Here, the body portion 1a is flexible and can be squeezed radially inward. A cylindrical mouth portion 1c is integrally connected to the upper end portion of the shoulder portion 1b, and a projection 1d is provided on the outer peripheral surface of the mouth portion 1c. An inner space S2 surrounded by the mouth portion 1c and a partition wall 1e separating the inner space S2 and the filling space S1 are provided inside the mouth portion 1c. A communication port 1f is provided to communicate with the space S1.

The check valve 2 includes a tubular wall 2a provided inside the mouth portion 1c, a plate-shaped annular wall 2b connected to the lower end of the tubular wall 2a and mounted on the upper surface of the partition wall 1e, and a plate-shaped annular wall 2b. A plate-shaped valve body 2c is located radially inside the wall 2b and covers the communication port 1f from above and is seated on the partition wall 1e. Here, a part of the outer edge of the valve body 2c is connected to a part of the inner edge of the plate-like annular wall 2b. configured to open.

The discharge cap 3 has a plate-like top wall 3a covering the mouth portion 1c above. A cylindrical peripheral wall 3b surrounding the opening 1c is provided on the outer edge of the top wall 3a, and a claw 3c that engages with the projection 1d is provided on the lower end of the peripheral wall 3b. As a result, the discharge cap 3 is attached to the mouth portion 1c so that it cannot be pulled out. In attaching the discharge cap 3 to the mouth portion 1c, the mouth portion 1c may be provided with a male thread portion, and the peripheral wall 3b may be provided with a female thread portion so that they are screwed together. A male screw portion 3d for holding the cover cap 4 is provided on the outer peripheral surface of the peripheral wall 3b. A tubular seal wall 3e is provided inside the peripheral wall 3b to contact the inner peripheral surface of the mouth portion 1c and the upper end portion of the tubular wall 2a of the check valve 2. As shown in FIG.

The discharge cap 3 also has a discharge port 3f having a predetermined shape and penetrating the top wall 3a. The ejection port 3f of the present embodiment is formed in a star shape as shown in FIG. 1(a). Furthermore, the surface of the top wall 3a is provided with a stepped portion 3g formed so as to recess the top wall 3a downward. The stepped portion 3g of the present embodiment includes all of the discharge ports 3f and is provided in a heart shape as shown in FIG. 1(a).

The cover cap 4 has a plate-like top wall 4a that covers the top wall 3a. An outer peripheral wall 4b surrounding the peripheral wall 3b is provided on the outer edge of the top wall 4a, and a female threaded portion 4c screwed into the male threaded portion 3d is provided on the inner peripheral surface of the outer peripheral wall 4b. Thereby, the cover cap 4 is detachably attached to the discharge cap 3 . Further, on the back surface of the top wall 4a, an annular seal projection 4d is provided that contacts the top wall 3a outside the stepped portion 3g when the cover cap 4 is attached to the discharge cap 3. As shown in FIG.

After the cover cap 4 is removed from the discharge container of this embodiment, the content can be discharged by squeezing the body portion 1a. Specifically, when the body portion 1a is squeezed, the pressure in the filling space S1 increases, and the valve body 2c separates from the partition wall 1e to open the communication port 1f as shown in FIG. 2(a). Therefore, the content of the filling space S1 flows into the inner space S2 and then passes through the discharge port 3f to be discharged onto the surface of the top wall 3a. Here, since the ejection port 3f of the present embodiment is formed in a star shape, the contents are also ejected in the same shape. Therefore, the amount of the content can be visually confirmed, and the shape of the ejected content can be visually observed and enjoyed.

Next, when the squeezing of the body portion 1a is stopped, the increased pressure in the filling space S1 is reduced, so that the valve body 2c is seated on the partition wall 1e to close the communication port 1f as shown in FIG. 2(b). . Therefore, even if the squeezing is stopped, the discharged contents remain on the surface of the ceiling wall 3a without being pulled back into the inner space S2. In addition, since the filling space S1 is closed and external air can be effectively prevented from entering, the quality of the contents accommodated in the filling space S1 can be maintained.

Thereafter, as shown in FIGS. 2(b) and 2(c), when the contents are scooped up by wiping the top wall 3a with a finger or the like, part of the ejected contents remains on the stepped portion 3g. Here, since the stepped portion 3g of the present embodiment forms a heart shape on the surface of the top wall 3a, the remaining content of the stepped portion 3g also has a heart shape. In this way, the shape of the contents changes from a star shape to a heart shape before and after scooping up the contents, so that the change in the shape of the contents can be visually enjoyed.

As described above, the present invention has been described while showing specific embodiments, but the discharge container according to the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. included.

For example, the shape of the discharge port 3f and the stepped portion 3g is not limited to the illustrated star shape or heart shape, and may be a circle, an ellipse, or a polygonal shape such as a triangle or a square. Also, various symbols and characters may be used. In addition, if the stepped portion 3g includes the entire ejection port 3f and has a shape different from that of the ejection port 3f as in the present embodiment, the change in appearance before and after wiping the contents becomes large. More preferably, the position where the stepped portion 3g is provided may be a location adjacent to or encompassing at least a portion of the ejection port 3f. Further, the shape of the stepped portion 3g may be the same as or similar to that of the discharge port 3f.

In the above-described embodiment, the ceiling wall 3a is provided with one discharge port 3f and one stepped portion 3g, but as shown in FIG. 3, a plurality of discharge ports 3f and stepped portions 3g may be provided. Also in this embodiment, the shape can be changed from a star shape to a heart shape before and after scooping up the contents, as in the case described with reference to FIG. In addition, in the embodiment of FIG. 3, the ejection port 3f and the stepped portion 3g are provided at regular intervals on the top wall 3a, but these may be provided at arbitrary positions on the top wall 3a.

Also, the check valve 2 is not limited to the one in which the valve element 2c is seated on and separated from the partition wall 1e to close or open the communication port 1f as in the present embodiment, and is, for example, spherical and movable within the inner space S2. may be provided to close and open the communication port 1f. Note that the check valve 2 is preferably provided in view of obtaining the above-described effect of the check valve 2, but may be eliminated.

Although the illustrated container body 1 is formed in the shape of a bottle, it may be formed in the shape of a tube. Further, the means for discharging the contents from the container body 1 is not limited to squeezing the container body 1, and may use a pump or a pressurized medium (aerosol).

Here, an embodiment using an HVD (High Viscosity Dispenser) as means for ejecting contents will be described with reference to FIG. In this embodiment, a cylindrical outer cylinder 11 , a bottom member 12 attached to the lower end of the outer cylinder 11 , and a bottom member 12 that abuts on the inner peripheral surface of the outer cylinder 11 and slides along the axis of the outer cylinder 11 . A movable inner plate 13, a cylinder 14 suspended from the upper end of the outer cylinder 11, a check valve 15 for closing and opening a communication port 14a provided at the lower end of the cylinder 14, and a cylinder 14. A cylindrical stem 16 disposed inside, a piston 17 that abuts against the inner peripheral surface of the cylinder 14 and is slidable along the axis of the cylinder 14 and supported downward by the stem 16, and an outer cylinder. 11 and the cylinder 14, and a holder 19 having a female threaded portion screwed to a male threaded portion provided at the upper end of the outer cylinder 11 and holding the cylinder 14 to the outer cylinder 11. a pressing head 20 having an inner cylindrical portion 20a connected to the stem 16; an elastic body 21 interposed between the holder 19 and the pressing head 20 to urge the pressing head 20 upward; and a cover 22 that is housed in a holder 19 and is detachably held by the holder 19 . Here, the pressing head 20 includes a top wall 20b connected to the inner cylindrical portion 20a, a discharge port 20c passing through the top wall 20b and communicating with the inner cylindrical portion 20a, and a stepped portion (second and a stepped portion (second stepped portion) 20e located above the first stepped portion 20d and having an outer shape larger than that of the first stepped portion 20d. The discharge container of this embodiment accommodates a relatively high-viscosity content inside the outer cylinder 11 and above the middle plate 13 .

In the discharge container shown in FIG. 4, when the pressure head 20 is pressed, the piston 17 is pushed down, which increases the pressure of the contents accommodated in the cylinder 14, so that the contents are discharged from the discharge port 20c through the stem 16 and the inner cylindrical portion 20a. object is ejected. On the other hand, when the pressure on the pressing head 20 is released, the pressing head 20 rises due to the urging force of the elastic body 21, and the piston 17 also rises accordingly. The communication port 14a closed by is opened, and the contents accommodated in the outer cylinder 11 are drawn into the cylinder 14. - 特許庁Therefore, when the pressing head 20 is pressed next time, the contents can be discharged in the same manner. Incidentally, when the contents are drawn into the cylinder 14, the middle plate 13 also rises accordingly. For this reason, the inside of the outer cylinder 11 will not have a negative pressure and the outside air will enter and the contents will not be exposed to the outside air.

According to such a discharge container, as shown in FIG. 4, it is possible to discharge the contents with the ceiling wall 20b facing upward, and conversely, the contents can be discharged with the ceiling wall 20b facing downward. You can eject things. Therefore, for example, when the outer shape of the ejection port 20c is star-shaped and the outer shape of the second stepped portion 20e is heart-shaped, the content is ejected onto the palm with the top wall 20b facing downward. As a result, the contents on the palm can be made into a star shape, and the contents remaining on the ceiling wall 20b after ejection can be made into a heart shape by the second stepped portion 20e. When the first stepped portion 20d and the second stepped portion 20e are provided to form a multi-stepped portion as in the present embodiment, for example, the content remaining on the second stepped portion 20e is lightly wiped off before the first stepped portion 20d is removed. By leaving the contents in the stepped portion 20d, it is possible to enjoy the change from the shape of the second stepped portion 20e (heart-shaped) to the shape of the first stepped portion 20d (eg, round shape).

The discharge container according to the present invention can discharge the content in the form of gel, foam, or paste by appropriately selecting the type of the content and the discharge means. In addition, it is preferable that the content to be used has a relatively high viscosity in that the shape formed by the discharge port can be maintained. can be seen and enjoyed. Therefore, in the discharge container according to the present invention, a strong customer attraction force can be exhibited regardless of the viscosity of the contained contents.
